getting results to use

    Hi Liam

    I love the idea of this plugin! So very useful however, when I try to call up the results for use on the front end using get_post_meta( $post->ID, 'dominant_color_hex', true ) I get nothing. Not even an empty array.

    With some combinations of various functions I can get the ‘alt’, ‘caption’, and ‘description’ of the image but nothing from the dominant colour plugin…

    It works perfectly in the admin and displays a colour palette for each image with the dominant colour selected.

    I have tried calling it from both within the loop and outside the loop both including and excluding the true/false parameter. Nothing.

    Any thoughts??

    Thank you.

    Hey kc,

    Sorry for the delay. What do you get if you:

    var_dump( get_post_meta( $post->ID, 'dominant_color_hex', true ) );

    Feel free to email me – [email protected] and we’ll get this sorted if you still need help!

    Thank you for getting back to me.

    var_dump returns :

    string(0) “”

    I have tried having the image set as just a featured image, both featured and inserted into the content area, and just in the content area. Same result for all three scenarios.

    I have updated the plugin and it still works perfect in the admin media library. Just no results on the front end…

    I thought it be good to keep this discussion here in case anybody else has the same issue.

    Thank you.

    For anyone having a similar issue, this is the solution that has worked for me:

    Are you calling the get_post_meta on the featured image ID, or the post’s ID? I guess my demo code there was misleading. Try:

    var_dump( get_post_meta( get_post_thumbnail_id(), ‘dominant_color_hex’, true ) );

    This works for getting rgb values also.
